Minor nit the copyright should be updated to 2019-2021

When disabling the dmadev drivers using -Ddisable_drivers=dma/* the 
rawdev driver isnt available to use for dma devices.

The way this is ATM if dmadev is disabled it doesnt build rawdev.

The logic should be - if dpdk_conf.has('RTE_DMA_IDXD') and 
dpdk_conf.has('RTE_DMA_IOAT')
